Three-pile lattice type combined tower crane foundation structure

Abstract

The invention discloses a three-pile lattice type combined tower crane foundation structure which comprises three vertical cast-in-place piles, three vertical lattice type steel columns and a concrete bearing platform located on the lattice type steel columns. The lower ends of the three lattice type steel columns are anchored in the three cast-in-place piles respectively, the upper ends of the three lattice type steel columns are anchored in the concrete bearing platform, a vertical bridging and a horizontal connecting rod are fixedly arranged between any two lattice type steel columns, and a plurality of tower crane anchor pins extending upwards are anchored in the concrete bearing platform. The three-pile lattice type combined tower crane foundation structure is good in foundation stability, simple in structure, low in manufacturing cost and safe and reliable.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a three-pile lattice combined tower crane foundation structure. Background technique [0002] At present, with the rapid development of the modern construction industry, the continuous updating of building construction methods, and the extensive use of new materials, more and more super-large and ultra-deep foundation pit projects have appeared. In order to solve the vertical transportation of such foundation pits, usually It is necessary to set up a conventional four-pile combined tower crane foundation structure in the foundation pit before excavation. However, sometimes the pile diameters of super high-rise buildings are large and dense, and they are constructed in an equilateral triangle. Adjust the arrangement of piles or increase the tower crane foundation. Pile is often very difficult. In this case, it is necessary to break through the routine and design a new type ...

[0002] At present, with the rapid development of the modern construction industry, the continuous updating of building construction methods, and the extensive use of new materials, more and more super-large and ultra-deep foundation pit projects have appeared. In order to solve the vertical transportation of such foundation pits, usually It is necessary to set up a conventional four-pile combined tower crane foundation structure in the foundation pit before excavation. However, sometimes the pile diameters of super high-rise buildings are large and dense, and they are constructed in an equilateral triangle. Adjust the arrangement of piles or increase the tower crane foundation. Pile is often very difficult. In this case, it is necessary to break through the routine and design a new type of tower crane foundation mechanism
